In this paper

the pure receiving end area is presented based on the premise of high voltage distribution network without distributed power sources. At the same time

for making the planning result more targeted

the study is classified into heavy load and light load so to analyze different demands of reactive power voltage control. Cataclysmic genetic algorithm is adopted to solve the model

which takes minimum yearly expenses including newly increased investment and network loss cost as objective function and takes the operating requirements of a various operation modes as constraints. Reactive power optimization calculation is performed by choosing several heavy-load and light-load pure receiving end area and the reactive compensation requirement of the receiving area at different loads is induced. The configuration ratio suggestion is raised

which can play better instructive role to the design and plan of project.
